Measure the spool against AMS 2 Pro’s listed 197–202 mm diameter and 50–68 mm width. Follow the manual’s cardboard-spool adapter guidance, and treat owner reports as mixed examples rather than a guarantee.
Check the spool dimensions first
Bambu lists AMS 2 Pro spool limits of 197–202 mm diameter and 50–68 mm width in its published specifications. ELEGOO’s Rapid PETG listing identifies a cardboard spool but does not give its diameter or width. Measure the spool you have against Bambu’s limits.
Why does Bambu recommend an adapter?
The AMS 2 Pro manual recommends a spool adapter for cardboard spools to reduce slipping and cardboard debris. Use the manual’s current instructions for the exact feeder. An adapter may change the effective diameter, so check that the assembled spool still fits and rotates freely.
What do owners report about ELEGOO and cardboard spools?
An owner discussion about ELEGOO cardboard spools in AMS 2 Pro includes people who run them without an adapter and others who describe dust, damaged edges, or a poor fit. These are individual setups, not a brand-wide guarantee.
This page answers whether a cardboard spool works in AMS 2 Pro; the cardboard spool and dryer guide compares cardboard and plastic reels across AMS, AMS Lite, and heated dryers. For other spool combinations, check the feeder compatibility table.
